Gaillardia plant named &#39;baltoryell&#39;

ABSTRACT

A new and distinct cultivar of  Gaillardia  plant named ‘Baltoryell’, characterized by its yellow-colored ray florets, light green disc florets and vigorous, upright, and mounded growth habit.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofGaillardia plant botanically known as Gaillardia pulchella andhereinafter referred to by the cultivar name ‘Baltoryell’.

The new cultivar originated as the product of the open-pollination, inNovember 1999, of the proprietary breeding selection designated‘NCT-137-2’ (not patented) with a mix of pollen from plants grown fromThompson & Morgan double Gaillardia mix (not patented). The newGaillardia was discovered and selected as a single flowering plantwithin the progeny of the above stated open-pollination during October2000 at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings takensince November 1999 at Arroyo Grande, Calif. and West Chicago, Ill. hasdemonstrated that the new cultivar reproduces true to type, with all thecharacteristics as herein described, firmly fixed and retained throughsuccessive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was repeatedly found that the cultivar of the present invention:

1. Forms yellow-colored ray florets and light green-colored discflorets, and

2. Exhibits a vigorous, upright, and mounded plant habit.

‘Baltoryell’ has not been observed under all possible environmentalconditions to date. Accordingly, it is possible that the phenotype mayvary somewhat with variations in the environment such as temperature,light intensity, and day length without, however, any variation ingenotype.

Of the Gaillardia cultivars known to the inventor, the most similar to‘Baltoryell’ is ‘Sundance’ (not patented). However, in side-by-sidecomparisons, plants of the new cultivar differ from plants of ‘Sundance’primarily in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonablypossible to make the same in color illustrations of this type, typicalflower and foliage characteristics of the new cultivar. The plants weregrown for 12 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is theR.H.S Colour Chart of The Royal Horticultural Society, London, England1995 edition, except where general terms of ordinary significance areused. The color values were determined on May 21, 2003 in West Chicago,Ill. The readings were taken between 10:00 and 11:45 a.m. under naturaldaylight conditions. The plants were produced from cuttings taken fromstock plants and were grown in a double polycarbonate-covered greenhouseunder conditions comparable to those used in commercial practice. Theplants were grown in 10 cm pots while utilizing a soilless growthmedium. Greenhouse temperatures were maintained at approximately 65°-75°F. (18°-24° C.) during the day and approximately 60° 65° F. (15°-18° C.)during the night. Greenhouse light levels of 5,000-8,000 footcandleswere maintained during the day. Plants were pinched at three weeks afterplanting. The following measurements and descriptions were taken at 12weeks after planting of rooted cuttings.
